[PATCH][next] tipc: Use size_add() in calls to struct_size()

If, for any reason, the open-coded arithmetic causes a wraparound, the protection that `struct_size()` adds against potential integer overflows is defeated. Fix this by hardening call to `struct_size()` with `size_add()`. Fixes: e034c6d23bc4 ("tipc: Use struct_size() helper") Signed-off-by: Gustav
